WASHER AND SHAFT.

Specification of Letters Patent.

Patented June 14, 1921.

Application filed February 24, 1919. Serial No. 278,972.

T0 all fw hom t may concern Be it known that I, SWAN R. S'rnoM, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in llfashers and Shafts, of which the following is a specification.

An object of the present invention is to provide a washer which is capable of longitudinal adjustment on a shaft and which is adapted to be held in preferred adjusted position on the shaft meansV of a pin or other suitable means which passes through a single hole in the shaft and through one pair of a plurality of pairs of holes in the washer which are spaced apart in a direction longitudinally of the shaft and also spaced at an angle to each other, thus providing a plurality of adjustments without making a plurality of holes in the shaft and consequent weakening of the same.

A more specific object of the invention is to provide a device for adjusting discharge door operating mechanisms to cars when the dimensions of such cars vary in a direction longitudinally of the mechanisms or in a direction longitudinally of the shafts for operatingsuch mechanisms, or when component parts of the mechanism on the shaft and discharge doors do not register.

Another object of the invention is to provide a discharge door Voperating shaft with meansV which will permit of the moving of the power applying device on the shaft a sufficient distance to compensate for varia tions in the length of the car body to which the shaft is applied and will hold such power applying device in preferred adjusted position.

A further object of the invention is to provide a discharge door operating mechanism withmeans which will permit of the moving of the discharge dooroperating shaft a suiiicient distance to compensate for variations in the length of the car body to which the shaft is applied and to move the door supporting rollers into their proper positions relative to the shoes which are secured to the doors.

Referring now to the drawings in which like reference charactersrefer to like parts, Figure 1 is an end view of a portion of a car and discharge door operating mechanism embodying the invention; Fig. 2 is a sectional view of the same taken on the line 2-2 of Fig. l a portion of the length of the car being broken away, the discharge door operating mechanism being shown in its preferred position; Fig. 3 is a similar sectional view showing the mechanism in an adjusted position; lis a side view of one of the washers; Fig. 5 is a face view of the same; Fig. 6 is a side view of another washer; and Fig. 7 is a face view of the same.

Referring now in detail to the drawings, 1 indicates the car body which may be of any desiredtype or construction, the car body illustrated in the drawings being of what is known as the general service type, and is provided with side walls 2, end walls 3, transverse underframe members i3 and discharge doors 5, all of which parts are of the usual form and construction.

The discharge doors 5 may be operated by the use of any suitable mechanism, but for illustrative purposes a mechanism has been shown in the drawings which is fully described in .United States Patent #791348 granted to Charles A. Lindstrom and John F. Streib May 30, 1905. This mechanism comprises a shaft 7 which preferably eX- tends in a direction longitudinally of the car and is operatively mounted in suitable bearing members 8 which are secured to the transverse underframe members 4. Between these transverse members 1 the shaft is provided with rollers 9 that are adapted to engage with shoes 10 which are secured to the doors 5. Each of these rollers is preferably provided with a spirally grooved drum l1 upon which a chain 12 is adapted to be wound7 one end of such chain being securet. to the drum and the opposite end being secured to the shoe member or to the door. VThe outer end portion of this shaft preferably extends beyond the end wall 3 and is provided with a ratchet wheel 13 and hand lever 14 or any other suitable means for rotating the shaft. ln the mechanism illustrated, the shaft, adjacent its outer end portion, is journaled in a bearing member 15 which int-urn is mounted in a member 16 which is preferably secured to the end wall 3. The ratchet wheel 13, hand lever 14 and bearing member 15 are held in their proper operative positions on the shaft relative to each other and to the end wall 3 by washers 17 and 18, the washer 17 engaging with the bearing members 15 and'16 and the washer 18 engaging with the hand lever 14. These washers 17 v(so and 18 are substantially alike, each having a sleeve portion i9 ancL a flange portion 20. The sleeve portion 19 of the Washer 17 is provided with pairs of holes 2l., 22 and 23 Which are each adapted to register with Va hole 24 in the shaft, such pairs holes being spaced apart longitudinally of the shaft and at an angle of substantially 6Go from each other. The Washer 18 is also provided With pairs of holes 25, 26 and 27 which are spaced inV the same manner as the holes in the Washer 1'? and are adapted to register with a` hole 28 in the shaft. Y

ln building a plurality of cars of the same type it has been found that the rollers 9 will not in all cases register with the shoes 10, due unavoidable inaccuracy in commercial production and heretofore it has, in many cases', been diflicult to apply the discharge door-operating mechanism to different cars of the same type Without drilling extra holes in the shaft .7 to enable the Washers to be secured to the shaft in such a manner as to compensate for such inaccuracies after the mechanism has been mounted on the car. By the use of the Washers 17 and 18 these extra holes in the shaft are rendered unnecessary, and it will be noted that `when the door operating mechanism is appliedA to a car in which the shoes on the door are in their proper positions relative to veach other and to component Vparts of the car as shown in full lines in Fig. 1 oi the drawings, a pin or other suitable means is passed through the pair of holes 22 in the Washer 17 and through the 'hole 24 in the shaft and a pin is passed f in Fig. 1 of the drawings the shaft together With the rollers may be moved, haeltward or forward until the shoes and rollers do register as shown in full lines in 1 and if it is necessary to move the shaft and rollers forward as shown in full lines in Fig. 2 to obtain such registration, a pinris lpassed through the pair of holes 27 in the Washer 18 and through the holes 2S in the shaft 7 and a pin is passed through the pair of holes 21 in the Washer 17 and through the hole 24 in the shaft 7, but if on the other hand it is necessary to move the shaft and rollers backward as shown in dot and dash lines in Fig. 2 to obtain such registration, a pin is passed through the pair of holes 25 in the Washer 18 and through the hole 28 in the shaft and a, pin is passed through the pair of holes 23 the 'Washer 17 and through the hole 24 in the shaft 7. It will here be noted that in this adjustment to different cars, the shaft and rollers only are moved, but it is to be understood that the povver applying device may be moved on the shaft to adjust the mechanism to oars of the same type which vary in length due to unvoidable inaccuracies in commercial production. Then the door operating lmechanism is applied to a car .viieh is of the proper length, a pin, or other suitable means is passed through the pair of holes 22 in the Washer 1T and through the hole 2li in the shaft and a pin is passed through the pair of holes 26 yin the ivasher 18 and through the hole 28 in the shaft, thus holding the shaft and the power applying device against longitudinal movement. lWhen the discharge door mechanism is to be applied to a car the length of which is shorter than that intended, a pin is passed through'the. pair of' holes 2l in the Washer 1? land through the hole 2li in the shaft and a pin is passed through the pair of holes 2T in the Washer 18 and through the hole 28 in the shaft. "N hen the discharge door mechanism is to be applied to a car the length of which is greater than that intended, a pin is passed through the pair of holes 23 in the Washer 17 and through the hole 2l inthe shaft and a pin is passed through the pair of holes 25 in the Washer 18 and through the hole 28 in the shaft.

rlhe Washers have been described in connection with What is vlrnovvn as the creeping shaft discharge door operating mechanism but it Will be understood that these Washers may be applied to a shaft to be used for any other purpose.
